Convert3dpolys in MAP3D

Dear all,

 

The perennial question of converting 3d polylines to 2d polylines. In Civil3D 2014 under modify there is a command to convert 3d polylines to 2d polylines.

 

Is there something similar for MAP3D 2014 or I need to resort to LISPs?

 

Thank you for your help.

 

Festive wishes

Hi,

 

you can use command _MAPCLEAN and in the third dialog activate the checkmark for "3D-Polyline to Polyline"

The resulting elements are then polylines (LwPolyline) with an elevation (I guess from the Z-value of the first vertex).

...or simply _FLATTEN the selected objects to the Z=0 plane.

The result will be a mashed 3Dpoly, explodable to lines.

Thank you for all the responses. The MAPCLEAN solution actually converts 3D Polylines to polylines making it possible to change linetype to dash dot etc.
The flatten alternative converts them in 2d but are still 3D polylines.
